HydroSure Adjustable DELTA™ End of Line - Spike Dripper - 0-6 L/h - Pack of 10
646 In Stock
Control dripper output by twisting the in-body key. The built-in spike anchors the dripper in place minimising waste and promotes accurate delivery. See Full Description
Easily adjust water output by turning the built-in winged key by hand – no tools required. Drippers can be turned off when not in use by turning the key as far as it will go clockwise. To increase the output, turn the key anti-clockwise half a turn per litre. Fully compatible with Water Butt Irrigation Systems and ideal for use in a garden irrigation system where plants require varying amounts of water.
Simple to Install and Maintain
Ideal for installation into 4mm micro-pipe at the end of a row of in-line drippers or singularly in a pot or hanging basket. Use the spike to anchor in position pointing to the plant’s roots. Keep your drippers in tiptop condition by fully unscrewing the in-built key from the dripper and clean in a bucket of water before reassembling.
Turbulent Flow Path
To protect against blockages, the drippers are equipped with an internal patterned labyrinth designed to maximise turbulence. This unique labyrinth forces water to spin and whirl around the dripper to ensure water is constantly moving. Ensuring particles do not have a chance to settle inside the dripper, protects against sediment build-up that leads to clogging.
UV Protection
Suitable for watering your vegetable patch as the dripper is manufactured from UV Stabilised polypropylene to ensure a longer life and prevent against deterioration when exposed to sunlight.
Optimal Performance
Adjustable drippers work most efficiently at water pressures around 1 bar – use a Pressure Reducer at the start of your system to regulate the pressure to the optimal level.
Time and Water Saving
Using a micro-drip system not only saves time but also uses up to 90% less water than manual watering and sprinkler systems. Drippers can be positioned to deliver water with pinpoint accuracy directly to the roots of the plant. Automate your irrigation system by installing a Water Timer so you can irrigate your garden even when you are on holiday!
Micro Drippers Frequently Asked Questions
Some of my Micro Drippers
are not working!
Common Problems
Drippers not emitting: Check the flow rate from the tap using our Water Pressure and Flow Rate Guide. A flow rate of 540 LPH and a Dripper output of 8 LPH means up to 67 emitters can be run in a single zone. (Flow Rate Divided by Emitter Output).
Dry spots: Emitters can become clogged with insects or dirt. Regularly flushing the pipe network, dismantling the drippers and cleaning them under running water prevents blockages.
Structural Damage: Digging in the garden can puncture the supply pipe affecting emitter performance. Locate leaks or water pooling and fix the pipe by cutting out the damaged section using Pipe Cutters and re-connect using a Joiner.
Pressure Loss: Make sure any open end of the pipe is plugged using an End Cap. This maintains water pressure at the correct level for emitters to function.
My Micro Drippers keep clogging and blocking!
Use an Irrigation filter at the start of your system to prevent naturally occurring sediment from clogging dripper outlets.
Drippers that Prevent Blockages
Drippers with a Check Valve prevent calcification of the internal pipe by keeping water in the system after it is switched off.
Self-Flushing Drippers have a turbulent flow patterned labyrinth preventing sediment from settling and flushing out unwanted debris.
How much does Micro Drip irrigation cost?
Components used to build a Micro Drip system are often inexpensive with a small system starting from around £24.
HydroSure Drippers, Pipe and Connectors are a built-to-last and cost-effective solution manufactured from durable UV-stabilised plastic offering resistance to deterioration from direct sunlight and harsh weather conditions.
Can I buy more Micro Drippers to extend my current
system?
Yes, simply connect the additional pipe using a Barbed or Nut Lock Joiner. Alternatively, 4mm Joiners and Micro Pipe can be used to tap into the wall of the LDPE Pipeto take drippers up to 10 metres away from the main supply.
How do I hold Irrigation Pipe and Drippers in
position?
Properly uncoiling the irrigation pipe helps with installation. Make pipe easier to work with by weighing it down on either end with a brick and allow any bends to settle. The pipe can then be secured into place every metre and at either side of where a dripper is positioned using Pipe Stakes.
Can a Dripper be inserted into garden hose pipe?
No, hose pipe is manufactured from flexible PVC that when punctured to insert a Micro Dripper frays the surface and does not create a watertight seal.
Instead, insert Micro Drippers into the wall of Irrigation Pipe. LDPE Pipe has a rigid wall that a Micro Dripper can lock into. Alternatively, use alongside Micro Pipefor installations up to 10 metres away from the main supply.
Will a Micro Drip System over winter or does it need to be
removed?
HydroSure Micro Drippers are manufactured from high-quality polypropylene and silicone to ensure longer-lasting durability. For this reason, Drippers can remain in position over the winter months.
Top Tip: Avoid the impact of thawing and freezing by removing the End Caps or using a Valve in place of an end piece. Run water through the system for around 2 minutes to flush out any debris.
Micro Irrigation Drippers vs Drip Line
Both Drippers and Drip Line regulate water flow based on the plant’s water consumption requirements. Whilst Drip Line is easier to set up, Micro Drippers enable flexible placement flower beds, planters, hanging baskets and pots rather than being confined to the pre-set spacings of Drip Line.
Drip Irrigation vs Micro Sprinklers and Spray
Sprinklers and sprays irrigate multiple plants from a single emitter whilst Micro Drippers use up to 80% less water and deliver it directly to the plant's roots where it is needed most.
